Applications

Features • Bronze corrosion resistant castings • Special cast bronze helical gears for quiet operation • Stainless steel shafts & fasteners • Positive displacement flow • Bronze bearing surfaces with grease fittings Liquids And Temperature Service life will be increased substantially if the liquid pumped is clean and has some degree of lubricity. These positive displacement pumps have tight tolerances. Fine abrasives like sand, silt, or powders in suspension will accelerate pump wear and reduce throughput. Liquids compatible with bronze and stainless steel can be pumped providing proper seal has been specified see chemical compatibility or check factory. No carbon bearings used. When possible, flush the pump after each usage. Temperature extremes are detrimental to service life and should be avoided. Basic metals of construction allow a temperature range of 40 to 400 F. Some lip seal elastomers have a limit of 212 F. see engineering data or check factory. Allowing a liquid to freeze in the pump can cause damage. Suction Lift Close tolerances and the positive pumping action make the rotary gear pump capable of lifting water on the suction side as high as 20 feet. Though gear pumps are self priming, a foot valve is recommended. If possible, wet the gears with liquid to be pumped for the first dry start. Liquid retained in the system and gear chambers serves to wet the pump on subsequent starts.
